Rough natural crystal (likely quartz or glass given appearance, but evaluated as a raw specimen)
Rough natural crystal (likely quartz or glass given appearance, but evaluated as a raw specimen) · Uncut raw crystal / Irregular elongated fragment
Not applicable (uncut rough specimen) Cut
Carat
Estimated 4-6 carats based on visual scale against fingers
Color
Near colorless to light yellow tint
Clarity
Included / Imperfect due to surface etching and internal fractures
Shape
Uncut raw crystal / Irregular elongated fragment
Overall Assessment
An interesting raw crystal specimen displaying natural geological features, requiring professional testing to definitively confirm diamond versus quartz or other transparent rough minerals.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low to moderate due to raw, unfaceted surface
Fire
Minimal due to lack of precision cuts and facets
Scintillation
Poor, as light diffuses through rough surfaces rather than returning via facets
Proportions
Non-standard raw elongated crystal proportions
Symmetry
Natural crystal growth symmetry, highly irregular
Polish
Raw, natural unpolished surface with growth lines and etching
Fluorescence
Unknown without UV testing
Inclusions
Internal feather fractures and potential mineral inclusions
Blemishes
Natural surface trigons, pitting, and irregular texture
Origin
Alluvial deposit or primary kimberlite/pegmatite rough indicator
Treatment Detection
No obvious signs of artificial enhancement; appears completely untreated
Estimated Value
Nominal specimen value, highly dependent on exact mineral composition and origin
Certification Estimate
Not typically certified by major labs (GIA/AGS) in raw form unless submitted as a specific rough study
Investment Potential
Low as a liquid gemstone, moderate as a collector mineral specimen

Setting Suggestions
Wire-wrapped pendant or organic raw stone bezel setting
Care & Maintenance
Store separately to prevent scratching other softer stones; clean gently with warm soapy water
Interesting Facts
Raw diamond crystals often feature triangular growth marks called trigons on their octahedral faces
